Abstract
The results of investigations of the stability of VOK-60 cutting ceramic during machining of hardened steel blanks made of No. 45 steel of different hardness 45 HRC and 54 HRC are presented. The stability of the cutting ceramic plate during machining of a harder blank is 41% higher than in machining of a less-hard blank. A microstructural analysis of the damage to the working surface was performed and the mechanism of wear of the cutting plate was determined. The reasons for the more rapid wear of the plate during machining of a less-hard blank were determined.
